IMPROVEMENT m EARTH-AUGERS.

Specification forming part of Letters Patent No. 176,029, dated April11, 1876; application filed January 7, 1876.

To all whom it may concern:

Be it known that I, BENJAMIN F. METZ, of Pittsburg, in the county of VanBuren, State of Iowa, have invented a certain new and useful Improvementin Angers, of which the. following is a description sufficiently full,clear, and exact to enable any person skilled in the art or science towhich my invention appertains' to make and use the same, reference beinghad to the accompanying drawing, forming a part of this specification,in which- Fignre 1 is an isometrical perspective view, and Fig. 2 abottom or end view.

Like letters of reference indicate correspond- -ing parts in thedifferent figures of the drawing.

My invention relates to that class of angers which are employed inboring wells, postholes, 860.; and consists in a novel construction andarrangement of the parts, as hereinafter more fully set forth andclaimed, by which a simpler, cheaper, and more efi'ective device of thischaracter is used than is now in ordinary use.

The nature and operation of my invention Will be readily obvious to allconversant with such matters from the following description.

In the drawing, A represents the main frame, which is provided with theshank B, and connected with the rod C. An outwardly-curved plate, H, ispermanently attached to one side of the frame, and arranged oppositethis there is a corresponding plate, G, which is hinged at h h. Thisplate is secured by a key and bolt at g i, and is hinged to enable theimplement to be cleaned'or emptied more readily. The plates, when inposition, form the body of the auger, which resembles in shape a hollowtruncated cone inverted. Projecting laterally from the frame. uponeither side are a series of slightly-curved,teeth or shares, I J, fordisintegrating the earth, and enabling the auger to bore withgreaterease and facility; and attached to the lower cross bar or end ofthe frame are two cutting pods or bits, K K, arranged as best shown inFig. 2. These bits are of the ordinary description, being provided withcutting-edges, and so shaped as to form the segment of a screw,

. which enters the earth as the rod 0 is turned.

Having thus explained my invention, what I claim is The improvedwell-auger described, con sisting of the frame A,'cur\'ed plates H G,provided with securing devices 2' g, teeth I J, bits K K, and rod 0,constructed and arranged to operate substantially as and for the purposeset forth.
